2. Background of Burj al arab hotel Meaning : Arabian Tower.
Location : sandy beach of Jumeirah, Dubai. Built 280m offshore of
private island Designed by Architect Tom Wright
3. Construction background Construction began in 1994 and
completed on site in 1999. Foundation built on sea.( took 3 years
to complete and 5 years construction period.) 321 meters high above
the sea level.
4. Design background Designed to create an icon for Dubai,
which represents urban revolution and to mimic the shape of Arab
Dhow, a type of Arabian Vessel. Shape of modern yacht sail to
reflect Dubais nautical heritage combined with a modern aspect
moving towards the future as a global tourists destination.
5. The types of structure High-rise atrium cantilever landing
pad truss
6. V shape concrete tower reinforced concrete tower used steel
bracing (Inner Reinforced Concrete V) for supporting. The front
(shore-facing) facade is the constructed of two tiers of huge,
steel X trusses.
7. Steel exoskeleton Two main structure of the exoskeleton is
the diagonal truss and Yacht structure The assembled segment were
lifted and erected in position using the tower cranes from ground
floor to top. Together the reinforced concrete and the exoskeleton
act as a composite and provide the structure horizontal stability
in all directions
8. Steel exoskeleton contd The diagonal trusses on the side of
the building are as long as a football pitch and weigh as much as
20 double-decker busses. They were built 15 KM from the site and
brought by road to Dubai on huge 80 wheel lorries which had to be
specially imported from South Africa. The highest truss took a day
to lift into place. If one man was to build the building himself it
would take about 8,000 years to finish.
9. Atrium The tallest atrium lobby in the world at 180meters
(590ft) It dominates the interior of the hotel, and takes up over
one-third of the interior space. The screen that encloses the third
side of the atrium is made of 1mm thick glass fiber fabric with a
Teflon coat to stop the dirt sticking.
10. Atrium (contd) The screen is the largest of its type and
covers an area of one and a half football pitch and it is hung from
the top of the building by over a kilometer of 52mm cable.
11. The material carbon fiber reinforced concrete glass fiber
Gold Steel Aluminium Marble
12. The Material(contd) The architectural materials of the
hotel consist of only a few mediums. Outside the exterior facade
consists of 50,000m2 of glazed curtain wall of 35,000m2 aluminum
cladding designed by Al Abbar Group. Glass and steel make up the
remaining portions of the exterior. The Steel structure was clad
with 6mm composite aluminum panels.
13. The Material(contd) The design is able to with stand a wind
load of 9kPa and was designed to drain water at each horizontal
joint. Inside the hotel the materials get even more expensive than
the outside. The interior features marble and 24 carat gold leaf.
Like the exterior, the interior steel structure is also clad with 6
mm composite aluminum.
14. Industrialized building systems (IBS) implemented during
the construction IBS- the building components(wall, floor slab,
beam, column, staircase) are mass produced either in factory/ at
site under strict quality control and minimal on site activities.
In order to reduce labors , improve construction's productivity,
reduce wasteful construction method, increase site safety,
environmental friendly, cost saving, speed up construction time.
Recognized as the worlds only 7 star Burj-al-arab is not just a
world-class luxury hotel, but also one of the most successful
project in Dubai which had implemented IBS during the construction
of the building. Main core area- using Cantilevers Top Climbing
Jump Form system. Cantilever Pty Ltd designed and supplied 300 ton
for the forming system. Wing walls & stair cores- using Dokas
SKE automatic-climbing form system. Doka designed the forms such
that only two climbing brackets per form are required.
15. Main floors-designed by Cantilever Pty Ltd.Designed as a
flying cable and supported by brackets attached to the walls.The
frame for the form was built with castellated steel beams and
measured 18.3m long by 8.1m wide. 18.3m x 8.1m. Meinhardt
international done the joint venture re-engineer the slabs to a
post tensioned design, it reduces the labors on reinforcing steel
and also time required to get enough strength to strip the
form.
16. How IBS helped in construction
17. Can be classified into 5 main groups: Pre-cast Concrete
Framing, Panel and Box Systems ~ most common IBS elements ~ e.g.
precast concrete columns, beams, slabs, walls, 3D components,
lightweight precast concrete and etc. Steel Formwork Systems ~
considered as the least prefabricated IBS. ~ e.g. tunnel forms,
tilt-up systems, permanent steel formwork (metal decks) and
etc.
18. Steel Framing Systems ~ commonly used with pre-cast
concrete. ~ always been the popular choice in construction of
skyscrapers. ~ e.g. steel beams and columns, portal frames, roof
trusses and etc. Prefabricated Timber Framing Systems ~ have their
own niche market. ~ normally used in simple houses. ~ e.g. timber
frames and roof trusses and etc.
19. Block Work Systems ~ have been revolutionized to achieve
more effective works. ~ e.g. interlocking concrete masonry units
(CMU) and lightweight concrete blocks
20. Benefits of IBS: to achieve higher quality products with
minimum wastages. helps to reduce the usage of timber formwork and
props. a safer and clean construction site. faster the completion
of the construction. minimize labour usage/ un-skilled workers.
reduce overall construction budget.
